The published guide counts 36 Supply Cache locations. Quartermaster’s official requirement is to unlock all Supply Cache items; visiting 36 locations alone does not prove the achievement is complete. Treat the location count as route information and the item unlocks as the achievement check.[1][2]

A COG Tag is a collectible entry, not an extra fifth checklist. Mark the item’s name and chapter when you find it so you can later identify a missing entry rather than only knowing your total is short.

Collectible totals by act

Published early-access chapter counts[3][4][5][6][7][8]

51 / 3 / 0 / 5 / 312Wiki Act 5 guide — ending spoilers

These totals sum to 140. Act 2 Chapter 3 has five entries: its screenshot guide’s heading says two, but its five item sections and Gameswelt’s independent list agree on five. Guides place Act 3’s final letter around the Act 3–4 transition; follow the named item as well as the chapter counter.[4][5][6]

Use the chapter index if you know the chapter name but not its number. The act guides include location spoilers; Act 5’s ending items are collapsed behind a spoiler warning.[8][9]

A simple sweep before the next transition

Suggested cleanup habit
  1. HEAR

    Pause after the fight

    Listen and look around before following the next marker.

  2. SEARCH

    Check the side route

    Look in nearby rooms, under paths and around the area’s edge.

  3. RECORD

    Mark the named entry

    Note its act and chapter in your checklist.

  4. COMPARE

    Check before moving on

    Compare your count before boarding transport or leaving the district.

Published gameplay guides identify a brief sound cue and controller vibration near collectibles. Some later items require side missions or story progress before their area becomes accessible. A marker or sound is a prompt to search; it does not tell you which completion category you have finished.[3][4]

Places worth checking carefully

Reported cleanup traps[4][6][7][10]
PlaceWhy to stop
Act 1 recruitment centerTwo items share the back-wall display area.
Act 2 Hold the Line27 items spread through an explorable district; some need side tasks.
Act 3 Last FootholdBlade-like Projectiles require the final side mission.
Act 4 Technical DifficultiesTwo items sit around a train stop before the train continues.
Act 4 Tough as NailsOptional routes include the Imulsion Blast Charge and factory closure sign.

Can I go back for a missed item?

Published gameplay guides describe chapter replay/new saves from selected chapters for cleanup. Keep your main save and match the missed item to its chapter before starting the replay.[6][8][10]

The launch update warns that joining another player’s existing save grants prior Secondary Objective and Hard Case progress in the War Journal and the related Forge rewards. It does not say every collectible automatically transfers, so check each category separately.[11]
